Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFRheostatic or dynamic braking:
- In this method, the electric motor is disconnected from the supply during the braking period and is reconnected across same electrical resistance
- The field winding is continuously excited from the supply in the same direction
- During the braking period all the kinetic energy of the rotating parts is converted into electrical energy and is dissipated across the electrical resistance
- Electrical energy not drawn by the motor during braking period
- It can be applied to both DC and AC motors
- It is very effective in the case of a separately excited dc motor
